添加代码片段：

settings --> user snippers --> new global snippers

官方示例：

{
  // Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and
  // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope
  // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is
  // used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
  // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders.
  // Placeholders with the same ids are connected.
  // Example:
  // "Print to console": {
  // 	"scope": "javascript,typescript",
  // 	"prefix": "log",
  // 	"body": [
  // 		"console.log('$1');",
  // 		"$2"
  // 	],
  // 	"description": "Log output to console"
  // }
}

说明：

scope: 需要应用的编程语言
prefix: 触发代码
body: 补全的内容，用$1等依次tab选取。
